More Information
Summary:The utility model discloses a multifunctional compound fuze circuit for a fire extinguishing bomb, which realizes the transmission of fuze and initiation control by using double microcomputers, simultaneously acquires an instant acceleration value of the fire extinguishing bomb by using an MEMS (Micro-electromechanical System) acceleration chip and judges to remove the protection for the fuze by using a time integral reaching an accelerate threshold. In the fuze circuit, one path of microcomputer finishes the communication information interaction with a control system according to different power-up states, or controls the fire extinguishing bomb to transmit and controls the head of the fire extinguishing bomb to fuze and power up as well as controls the fire extinguishing bomb to initiate and the like; and the other path of microcomputer is combined with the MEMS acceleration chip to finish the protection and protection removal of fuze initiation control and realize the functions of a full electronic safety
